Really? I quit calling time to clean the plate years ago! I see no reason to do so! My partner can handle the bases for a few seconds without my assistance! I consider guys that DO call time every time to be "Smitty's" because it seems that only a Smitty feels the need to kill the ball to do a bit of sweeping UNLESS he is working by himself. In that case, indeed, it would be very prudent to call time to clean the plate, although truthfully, I probably still wouldn't.

The play DOES stand. I have never seen anything anywhere that requires the umpire to call time to clean the plate. If the defense is not situation aware, that is not my problem.
